  Peter Lynch's One Up On Wall Street — an executable toolkit that applies
  Lynch's legendary investing framework: invest in what you know, identify
  tenbaggers, categorize companies by type, and build a winning portfolio
  using the edge that individual investors have over professionals.

  Covers 5 use cases:
  ① Stock Picking Fundamentals — use everyday knowledge to find great investments ("How do I pick winning stocks" "I want to invest in what I know")
  ② Company Categorization — classify stocks into six types ("Is this a growth stock" "What kind of stock is this")
  ③ The Perfect Stock — identify tenbagger characteristics ("How to find a stock that could 10x" "What makes a stock a multi-bagger")
  ④ Buy & Sell Timing — know when to buy more, when to sell ("When should I sell a stock" "Is it time to buy more")
  ⑤ Portfolio Building — construct a diversified portfolio for your goals ("How many stocks should I own" "How to build a retirement portfolio")

  Trigger when users say: "Peter Lynch" "One Up On Wall Street" "How to pick stocks"
  "Tenbagger" "Invest in what you know" "Stock market investing" "Value investing"
  "Growth stocks" "Stock categories" "When to sell a stock"
  "How to research stocks" "PEG ratio" "P/E ratio"
  or mention: Peter Lynch / One Up On Wall Street / tenbagger / stock picking /
  Fidelity Magellan / growth stocks / value investing / earnings /
  P/E ratio / PEG ratio / company types / buy what you know / dumb money.

## Philosophy — 5 rules to remember

1. **Invest in what you know.** Your everyday experience gives you an edge over professionals. The best stocks are often right in front of you — products you love, stores you shop at.
2. **Look for tenbaggers.** A tenbagger returns 10x your investment. They come from small, fast-growing companies, not from what's already popular.
3. **Know what you own.** If you can't explain your stock in two minutes, you don't understand it well enough to own it.
4. **The market does not know everything.** Stock prices fluctuate for reasons unrelated to company value. Ignore the noise.
5. **Time is on your side.** The stock market rewards patience. Buy great companies and hold them for years.

## Core Framework Quick Reference

- **Tenbagger** = A stock that returns 10x your investment. Found among fast-growing small companies, not popular large ones.
- **Six Categories** = Slow Growers (2-4%), Stalwarts (10-12%), Fast Growers (20-25%), Cyclicals (boom/bust), Turnarounds (distressed to recovered), Asset Plays (hidden assets).
- **The Perfect Stock** = Dull name, boring industry, niche product, employees buy it, company buys back shares, low P/E, high insider ownership.
- **The Two-Minute Drill** = Explain your investment thesis to a 10-year-old in two minutes. If you can't, you don't understand it.
- **PEG Ratio** = P/E divided by growth rate. Under 1.0 = undervalued. Lynch's favorite metric.
- **P/E Ratio** = Price / Earnings. The most important valuation number. Compare to industry and history.

## Key Principles

1. **Buy what you know.** Your consumer experience is research. The Dunkin' Donuts you love may be a better investment than the stock your broker recommends.
2. **Know the story.** Every stock has a story — why it will grow, why it's undervalued, why it will turn around. If you can't tell the story, you don't own the stock.
3. **Earnings drive stocks.** Over the long term, stock prices follow earnings. Focus on companies with growing earnings.
4. **Ignore the noise.** Market predictions, pundits, and daily price moves are distractions. Focus on the company.
5. **Patience pays.** The best stocks are held for years, not months. The greatest returns come from waiting.
6. **Know when to sell.** The story changes? Sell. The fundamentals deteriorate? Sell. The stock reaches full valuation? Consider selling.

## Anti-Pattern Summary

The book's core correction: Most individual investors think they're at a disadvantage to Wall Street. In reality, they have the edge — if they invest in what they know, ignore market noise, and focus on company fundamentals. See `references/4-anti-patterns.md`.

### Invocation Test

Test with: *"I'm new to investing. I have $10,000 to put in the stock market but I don't know where to start. Everyone says to buy index funds but I want to pick individual stocks like Peter Lynch."*

Expected output: Start with the most important principle: invest in what you know. Make a list of companies whose products you love and understand. For each one, ask: 1) Is this a company I can explain in two minutes? 2) What category is it (slow grower, stalwart, fast grower)? 3) What's the P/E ratio and growth rate (calculate the PEG)? Peter Lynch recommends starting with a small portfolio of 3-5 stocks from industries you understand. But don't ignore index funds — Lynch himself recommends that most of your portfolio be in index funds, with only a portion in individual stocks where you have conviction. Start with 80% index funds, 20% individual stocks. + Watermark.
